I have need of rendering text manually to a UIView, along with graphics.
I realise that I could probably use a UITextView as a subview and
position it, but for now I'd like to learn the right way to render it
manually.
My aim is to render a particular string in a particular colour, in a
particular font (or, any Sans Serif of the system's choosing would be
enough here) and a particular font size.
First, a quick question about +stringWithFormat: If I want to have a
literal string as one of the parameters to the format, which is correct
/ best:
NSString *textToDraw = [NSString stringWithFormat: @"%s",
"my string"];
or
NSString *textToDraw = [NSString stringWithFormat: @"%@",
@"my string"];
(or something else?).
Now, I'm led to believe that you can either use CGContextXXX calls, or
Cocoa text drawing. I seemed to fall flat on my face with the Cocoa way,
so I was trying to use this:
CGContextShowTextAtPoint(contextRef, 0, 40,
[textToDraw UTF8String], [textToDraw length]);
(since -cString: is deprecated). But I end up with garbage characters
and I don't know if I'm using +stringWithFormat: incorrectly, or
CGContextShowTextAtPoint().
What is the 'correct' or best recommended way to render text, lines and
filled primitives? For the Cocoa way of rendering text, how do I control
font face / size? The sample I found used NSDictionary for the
attributes but it won't compile the NSFontAttributeName the (web) sample
used for the key.
Thanks in advance.
